Faulty CFTR gene and CFTR proteins not being produced or function properly.
These actions can inhibit the effectiveness on the cell membrane.
In my opinion, if the density of the ocean water increase, D=m/V, let d mass be constant, the volume of H2O might be decreasing. Therefore volume will be the same as concentration of water. The water will flow from higher to lower concentration of water region in terms of con;for example the region of low density will flow to high density region. This is my idea and not the actual answer.
While the sequence of DNA may not be affected by your environment, the way genes work—called gene expression—can. ... Environmental factors such as food, drugs, or exposure to toxins can cause epigenetic changes by altering the way molecules bind to DNA or changing the structure of proteins that DNA wraps around
Answer: The fluid mosaic model described the plasma membrane that:
A membrane has proteins and other components embedded among the phospholipids.
Explanation: In the fluid mosaic model, phospholipids form a lipid bilayer in which the nonpolar regions or the fatty acyl chains of the lipids face each other at the core of the bilayer and their polar head groups face outward. The fatty acyl chains in the interior of the membrane form a fluid hydrophobic region while the proteins float in the sea of lipid held by hydrophobic interactions with their nonpolar amino acid side chains. Some proteins are embedded in this lipid bilayer protruding from only one side of the membrane while some have their domains exposed on both sides. The domains of proteins exposed on one side of the bilayer are different from the ones exposed on the other side, giving the membrane sidedness and also reflecting functional asymmetry. Both proteins and lipids are free to move laterally in the plane of the bilayer, but their movement from one face of the bilayer to another is restricted.
A covalent bond
A covalent bond happens if the attractions are strong enough in both atoms and if each atom has room for an electron in its outer energy level
